解磷、钾功能性微生物耐盐效应研究

open access: yesShuitu Baochi Xuebao, 2020
围绕设施菜田土壤盐渍化问题,以解磷、钾功能微生物胶质芽孢杆菌和巨大芽孢杆菌为研究对象,探究了盐分胁迫对功能菌活性、解磷钾能力的影响,并阐明了含2种功能菌微生物菌剂在轻度盐渍化设施菜田的作用效应。结果表明,混合功能菌最大耐受盐浓度为10.5% NaCl,最适宜生长盐分浓度为0.5% NaCl,且解磷、钾能力最强,有效磷、钾增幅分别为52.06%,75.41%;此外,轻度盐渍化设施菜田的小区试验结果显示含2种功能菌的菌剂可提高番茄、甜瓜、西瓜果实VC和可溶性糖含量,分别增产104.81%,23.72%,28.

Endometrial assessment in abnormal uterine bleeding: transvaginal ultrasound alone may not be good enough

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 1, Page 79-88, January 2026.
ABSTRACT Objective To evaluate the proportion of optimal assessments of endometrial thickness (ET) achieved by transvaginal ultrasound (TVS) compared with a multimodal (MM) sonographic approach in women with abnormal uterine bleeding (AUB). Methods This prospective observational study was a subset of the EPI‐SURE study conducted between June and ...

Finding floral and faunal species richness optima among active fire regimes

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Changing fire regimes have important implications for biodiversity and challenge traditional conservation approaches that rely on historical conditions as proxies for ecological integrity. This historical‐centric approach becomes increasingly tenuous under climate change, necessitating direct tests of environmental impacts on biodiversity.

Facilitating Large‐Scale Bird Biodiversity Data Collection in Citizen Science: ‘Relaxed’ Point Counts for Anytime, Anywhere Monitoring

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
This paper proposes a ‘relaxed’ point‐count survey method to enhance accessibility and expand geographic coverage by easing these constraints. Surveys can be conducted in diverse locations, including urban areas and travel routes, within flexible timeframes (e.g., 6 h after sunrise or during the evening) and with adaptable spacing between survey points,

轻烃催化转化制取低碳烯烃方法

open access: yes, 1992
一种轻烃催化转化制取低碳烯烃的方法是采用含有周期表ⅠA、ⅡA,第四周期,Mo、La或Ce中一种或几种元素为活性组分的ZSM沸石催化剂,在同一反应中使轻烃进化催化氧化脱氢裂化反应制取低碳烯烃。该技术适用于从较难裂化的低碳烷烃制取乙烯和丙烯,它比一般液态烃热解制烃的温度低150~200℃,且烯烃选择性好,收率高。同时由于催化剂制备过程进行硫化处理,催化剂催化性能稳定,寿命长 ...

Dermoscopic evaluation of normal canine skin with a handheld dermoscope

open access: yesVeterinary Dermatology, Volume 36, Issue 5, Page 593-601, October 2025.
Background – Dermoscopy is a noninvasive diagnostic tool that provides a magnified view of skin structures. While dermoscopy is described for certain canine dermatological diseases, large‐scale studies evaluating normal skin are lacking. Hypothesis/Objective – This study aimed to correlate dermoscopic findings with histopathological results in healthy ...
